Comment # 1 on bug 1224145 from Neil Rickert

Checking here, the GDM selection menu gives me:

Gnome
Gnome Classic
Gnome Classic on Xorg
Gnome on Xorg
IceWM Session
Plasma (X11)
Plasma (Wayland)

The first two of those are actually using Wayland, even though it does not
mention "Wayland" in the menu item.
